Step-by-step explanation:
Volume of a cylinder : πr^2*height.
Volume : 150cm^3
height : 7.2m
π =3.14
150 = 3.14*r*r*7.2
150=22.608*r*r
r^2= 150/22.608
=150/23cm^2
r=√6.5
r=2.569cm
r=2.6cm
Answer:
q1: yes
q2: no
Step-by-step explanation:
2(5)+10(1)=20
10+10=20
20=20
(5)+(1)=6
5+1=6
6=6
(8)=(1)+3
8=1+3
8=4
Answer:
-7
Step-by-step explanation:
We first are going to flip the equation around.
So instead of 9 times x = -36 we'll do 36/9. 36/9 = -7.
Also you will kind of know it will be a negative number from the beginning since it's -36.
I don't know if that last part makes any sense, but I hope this helps you!
Answer:
Dilations produce similar figures because the image and pre-image will have congruent corresponding angles. The corresponding side lengths of the figures will be proportional based on the scale factor. The shape is preserved and the sides are enlarged or reduced by the scale factor
Step-by-step explanation:
Answer: a) 236,000.
b) 2021
Step-by-step explanation:
Given : Population Growth The population P (in thousands) of Oriando,Florida from 1980 through 2009 can be modeled by 
(1)
where t = 0 corresponds to 1980.
Then , for 2009
t= 2009-1980=29
a. ⇒The population of Phoenix in 2009 = 
Hence, the population of Orlando in 2009 was about 236,000.
b) Substitute p= 300 in (1) , we get
(Divide both sides by 130)
Taking Natural log on both sides,
Hence, The year Orlando will have a population of 300,000 =1980+41 =2021
